COUPLING DEVICE FOR TIRE SIDE CHAINS.

v Specification of Letters Patent.

Patented Apr. 2%, 191?.

Application filed October 10, 1914. Serial No. 866,115.

To all whom it may concern:

Be it known that 1, WILLIAM HENRY VVILLIAMs, a subject of the King ofGreat Britain, residing at Bromford Lane, Erdington, Birmingham,England, managing director, have invented a new and useful CouplingDevice for Tire Side Chains; and I do hereby declare the following to bea full, clear, and exact description of the same.

This invention comprises improvements in coupling devices for tire sidechains for attaching automobile tire covers which are so worn as to beincapable of being used separately to the tires already in use on thevehicle.

In order that the invention may be readily understood and carried intopractice, reference may be had to the accompanying drawings illustratinga convenient embodiment of the invention.

In the drawings: 7

Figure 1 is a perspective view of a portion of an automobile wheel withmy invention applied thereto. Fig. 2 is a side view showing the couplingdevice in the screwed in or fully contracted condition. Fig. 3 is asimilar view showing the device in the fully expanded condition. Fig. 4is a View in a direction at right angles to that of Fig. 3. Fig. 5 is alongitudinal section on line V-V of Fig. 4.

In the construction illustrated the socket member 1 is produced from atube portion or pressed up cup open at one end to receive the screw 2 onone end of the chain 3 but closed or blind as at 4 at the other end. Thediameter of the socket 1 toward the open end is reduced a suitableamount by any suitable means, preferably in closing press tools, andthis reduced portion 5 is internally threaded to receive the screw 2 andis preferably provided with a hole or perforation 6 transverselytherethrough whereby the threads of the screw 2'are visible and pastwhich the screw 2 should not be withdrawn, instructions to that effectbeing if desired stamped or otherwise formed on the outside of thesocket. blind end 4.- of the socket is provided with a centralcylindrical projecting portion 7 which is passed through acorrespondingly sized perforation in a swivel member 8 after which it isriveted over at 9, so as 'to prevent withdrawal, a thin washer beinginterposed between the head thus formed and the The other or surface ofthe inturned portion 11 of the swivel 8. This latter is attached bymeans of a pin 12 and nut 13 to the corresponding end link of the chain3. To enable rotation of the socket 1 the same is made hexagonal inshape on its outer surface as clearly shown in Figs. 2-4 so as to beoperable by a spanner. The screw 2 is attached to the other end link ofthe chain in a similar manner by a pin 14 and nut 15.

What I claim then is:

1. As a tension adjusting device for the retaining members of auxiliarycovers for pneumatic tires, an adjustable coupling comprising a screwthreaded plunger, an interiorly threaded tubular socket portion, intowhich said plunger is adapted to be screwed, said socket portion beingopen at one end and blind at the other, the blind end of the socketportion having an integral projection for forming a swivel connection,and the said socket portion being also reduced in diame ter toward theopen end and being formed externally in the sha e of a nut.

2. As a tension a justing device for the retaining members of auxiliarycovers for pneumatic tires, an adjustable coupling comprising a screwthreaded plunger, an interiorly threaded tubular socket portion, intowhich said plunger is adapted to be screwed, said socket portion beingopen at one end and blind at the other, the blind end of the socketportion having an integral projection for forming a swivel connection,and the said socket portion being also reduced in diameter toward theopen end and being formed externally in the shape of a nut, and providedwith a small hole transversely therethrough near its open end for thepurpose set forth.

3. As a tension adjusting device for the retaining members of auxiliarycovers for pneumatic tires, an adjustable coupling comprising a screwthreaded plunger, an interiorly threaded tubular socket portion intowhich said plunger is adapted to be screwed, said socket portion beingopen at one end and blind at the other, the blind end of the socketportion having an integral projection for forming a swivel connection,and the said socket portion being also reduced in diameter bothexternally and internally toward the open end and being formedexternally in the shape of a nut along its entire length. I

socket portion having 4. As a tension adjustin device for the retainingmembers of mm iary covers for whic said plunger is adapted to bescrewed,

said'vsocket portion being open at one end and blind at the other, theblind end ofthe an integral projection for forminsia swive connection, apresse metal ringl e swivel member through which said projectionextends, said projection being rlveted over to prevent the withdrawalmember and said projection, said pressed member having arms thereon, andsaid socket portion being also reduced in diamev ter toward the open endand being formed externally in the shape of a nut.

whereof, I have signed my 20 In testimony name to this specification inthe presence of two subscribin witnesses.
